To all whom it may concern: l

Be. it known that "I, LUDWIK MARszALnK, a citizen of the RepublicofflPoland,.residing at Passaic in the cou'ntyof Passaic and State ofNew jersey, have inventednew and useful Improvements-inRailroad-Switches, of which the following is a specification.

This invention relates to improvements in switch operating mechanismsand has for an object the provision of means actuated by an approachingcar or train .for automatically throwing the switch.

Another obj ect is the: provision. of means controlled by a caror'train', whereby the switch points may be moved either toclose thetrack of the mainline or to close the siding track, irrespective of theprevious position of said switch points.

v Another object-is the provision of means controlled by a car or trainfor resetting the] switch or for moving the points in either direction,after the passage ofthe car or train, so as to open or close either themain track orsiding forthe yconvenienceof a .car or train following. j IlVith the. aboveandother objects in view, the invention further includesthe following novel features and details ofconstruction, to behereinafter, more-fully described, illustrated in the accompanyingdrawings and pointed' out in the claims hereto-appended.

. In the drawings Figure 1 is. a plan-view'of a section of a railwaytrack and switch showing lthe application of the invention.

Fig. 2 is a transverse section taken approximately on a line with theswitch set ting mechanism and showingwthe train carried device foroperatingthe same.

Fig. 3 is a fragmentary section takenlom gitudinallyof this end of the.trackand also showing-the train device. V p

1 Referring to the drawings in detail, whereln 1 like characters ofreference denote corresponding parts, the numeral 10. indi-.

cates the rails .ofthe main track and ll'the rails of the siding,whilethe switch are indlcated' by the numeral 12.

.. Located inthe advance ofthe switch is a mechamsm to be'hereinafterreferred to as r the switch setting mechanism,- indicated in itsentirety by the numeral 13, while at the opposite end of the switch andat a suitpoints able distancetherefrom is amechanism'to be hereinafterreferred toas the switch resetting mechanism and indicated in itsentirety by the numeral 14. The switch setting mechanism I atransversely disposed slidable rack bar 15, which is l'ocate'dbeneaththe track and preferably to one side thereof and it is shown asoperating within the casing. or housing 16. The rack bar 15 is providedwith a;

downwardly extending right angular .portion '17, which has pivotallyconnectedto-its lower extremitya link 18. This link is also pivotallyconnected to the lower end of a 'to one another. and having their endsremote from the arms 22; pivotallysecured to the roadbed between therails as indicated at :24. I The track devices 23 are also con nected tothe casing orho'using 16 by means oflinks 25, so that a downwardpressure on eitherjof the track devices will ;move the T-shaped lever 19upon its pivot and 13 names a through the medium of the link 18:.Will

move theraclrbar 15 transversely of the track.

The resetting mechanism 14, which is located beyond the switch alsoincludes a transversely movable rack bar26, which like the rack .bar 15is provided with a downwardly extending arm 27. Pivotallyuse stantiallysimilar to the lever 19 previously described and like this lever ispivotally mounted as shown at 30 between the rails of the track.Pivotally secured to. the laterally extending portions 31 of the lever29,

is a substantially L-shaped link 32, the latter extending outwardlybeyond the sides of the track and being pivotally mounted be tween thewalls of the casing or housing 33, which also receives the lever 29 andwhich extends transversely of both the main track .and the siding.

Pivotally mounted adjacentone of the rails of the main track 10, asindicated'at 34, is one end of the lever 35, which will also behereinafter referred to as a track device, while extending from thislever within the casing or housing 33 and connected to one of theL-shaped links 32, is a bar 36. A downward pressure of this bar by thewheels of thecar passing over the main track will depress the trackdevice, the lever '35 and swing the lever 29 upon its pivot to slide therack bar in one direction. Pivotally mounted adjacent one of the railsof the siding 11 as shown at 37, is a lever 38, the latter being alsoprovided with a downwardly extending bar 39 for connection with theother L-shaped link 32 and provid ing an additional track device {forengagement by-the wheels of the car passing over the rails of thesiding, so as to" rock the lever 29 and movethe rack bar 26 in an 0posite direction.

Iounted in suitable bearings4O and disposed longitudinally of the trackis a rock shaft 41, thelatter 'being provided at each end with a toothedsegment 42 for engage- .ment with the teeth formed in the upper For thevpurpose of selectedly actuating the track device 23, there is provideda train carried device 46. This device includes a pair of oppositelymovable vertical slidable roller carrylng members 47, the rollers 48 ofwhich are so spaced as to engage one of the track devices 23. Themembers 47 are provided upon their opposed faces with teeth 49, whichare engaged by toothed segments 50 carried by a transversely extendingshaft 51. This shaft is rotated will move the members 47 vertically inopposite directions so as to bring either one of said members intoposition for en- I actuated through the medium of suitable connectionsfrom a convenient point of the car and when the track devices 23. Thiswill rock the T shaped lever 19 upon its pivot and will,

through the mediumoof the rack bar 15., rock the shaft 41. This shaftwill in turn actuate the rack bar 26 and rock the lever 29 upon itspivot. This movementof the lever 29 will raise the track device 35'uponthe side ofthe track opposite to the track devices 23 of the switchsetting mechanism, so that the wheels of the car after passing over theswitch will depress/the said track device 35 andreset the switch in itsoriginal position.

The invention is susceptible to various changes in its-form, proportionsand manual details ofconstruction andthe right is herein reserved tomake such changes as properly fall-within the scope of the claims.

Having: described the invention, what is claimed isz? 1 1. Thecombination with a railway switch, of a car actuated switch-settingmechanism located in advance of the switch. and" ineludinga rock shaftdisposed longitudinally of the track,-z. rneans for connecting theswitch points totherock shaft, wherebyop eration ofgthe latterwillmove-:the switch points to set theswitch, a transversely mov ablerack bar for operating the rock shaft, a pivoted T-shaped lever locatedbetween the railsof the track, spaced parallel levers 1 0 having one oftheir ends pivotally secured betweenthe rails and. extending" longitudinallyof-the latter, right angularly disposed downwardly extending armsrigidly secured to said levers and engageable in notches provided in theT-shaped bar and means located beyond the opposite end of the switch forreturning the latter to normal position. 2. Thecombination' with arailway switch, of ,a car actuatedswitch setting mechanism locatedinadvance of the-switch andinclud- I ing a rock-shaft disposedlongitudinally of the track,.means forconnecting the switch points'tothe rock shaft, whereby operation r of the latter will move the switchpoints, a 115 transversely movable rack'bar for operating the rockshaft, a pivoted T-shaped lever located between the rails of the trackand pivotally mounted car operated levers disposed longitudinally of the'trackand engageable 12( upon the opposite sides of thepivot of theT-shaped lever for rocking the same in either direction, and meanslocated beyond the opposite end of the switch for returning the latterto normal position.

The combination with a railway switch, of transversely movable rack barsdisposed at opposite ends of the switch; a T-shaped lever mounted forpivotal =movement between the rails of the track at each end of 1311,350,373 1 7 r I V v 3 the switch and operatively connected to themeans operatively connecting. the rack bar, rack bars, car actuatingmeans located upon and a car carried device for selectedly operoppositesides of each of the T-shaped levers ating either of the car actuatedmeans to 10' for rocking the same upon their pivots to move theswitch-points in either direction move the rack bars in eitherdirection, from opp s te Sides of the switch means for connecting eachof the track bars In testimony whereof I aflix my signature.
